Testing Clay in a BBQ! Wondering How To Fire Clay Without A Kiln? TKOR Details EVERYTHING! 

“Clay... I’m sorry but I’m gonna have to let ya go” There. Clay is now fired😆

should have FULLY allowed clay articles to AIR DRY! slow moisture purge and evaporation. THEN fired. the remaining moisture in the clay caused your crackings!

Just a quick tip. Like you said, the only ones that broke were the coil pots. Thats probably because they weren't held together well. If you're doing coil, you have to use something called slip which is usually just clay mixed in water. It should be like a paste. You would use that as a glue to keep pieces together. More importantly, you made them as one coil. When doing coil, it should be done one coil at a time not just a long coil. That long coil prevents you from being able to score and slip then together. Scoring means putting marks in the clay so that the slip binds them together better. If you try that, it should prevent extreme cracks like yours was. Much love, someone who just finished his first semester in which he took a ceramics class. Hope that helped.

You're supposed to knead clay while wedging it. Throw it down then push forward and roll it up then repeat. Also slip and score the coils or they won't hold together and don't forget to pinch the coils together to bind them together.

As someone who does ceramics and goes on the wheel a lot, your “wedging” drove me crazy

It may have cooled too quickly, clay and glass firing equipment usually has fire-brick surrounding the firing area to insulate it, and let it cool way more slowly than the bbq cools... a bbq will be cool to the touch in a matter of an hour after the fire dies, where the fire-brick ovens that fire glass and ceramics will stay warm for much longer than that...

You need to score it and use slip also try need in it differently

You should ask some tips for *Primitive Technology*

Dude do some experiments with a laser

NO DONT FIRE ME I CAN HELP THE COMPANY!

*Art student screaming* You didn't Slip, Score, Seal!

Neighbors: Hey, watcha grilling over there? King of Random: ...Clay...

Mix negative x with thermite then add water

The clay is on fire 🔥

This video crushed my soul on so many levels. Internally yelling at how wrong some of these methods are

Wheel Potter - Thoughts on clay cracks - All clay has a percentage of shrinkage when it dries and when it fires. this can be anywhere between 4% to 15% shrinkage. Depending on the size of a piece this can be very minimal (1/4") to over an inch worth of a difference. A piece that has thinner spots vs thicker spots will dry at different rates and change how the piece shrinks uniformly. If a part of the pot shrinks faster than another part, it will separate causing a crack. The Clay needs to dry slowly until it is ready to fire to help prevent cracking. Porcelain is a very fine clay with no grog, it is quite strong when fired, but it also shrinks the most because as it dries the clay particles pack together tighter. The more grog that is included the less shrinkage you will have. Primitive technology was able to quickly dry his pieces by a fire due to the large amount of grog and impurities in his clay that prevented the clay from shrinking so much. A method that I use to help dry slower is to place a bucket, or other solid container, upside down over the piece, on top of stilts to allow a small slit of airflow from the bottom. I've used popsicle sticks, or even 1" thick blocks to raise the upside down bucket a bit. This creates a sort of "damp box" that prevents the moisture from escaping too quickly. Depending on the gap in your bucket, you can extend the drying time up to a few weeks.

Please can you make a backyard kiln?

What happens if you put clay in a vacuum chamber?

As a Potter I found it entertaining to watch this! I'd be curious to see an attempt at a proper pit fire and possible glazing!

As a ceramics student I was going: AAAAAAAHHHHHHHHH! The entire time.

You guys should do glass blowing in the foundry

Can you put bubble wrap in vacuume

Two things I notice. One was your wedging technique. You're supposed to toss it through a stretched wire or fishing line onto a table then knead to further work out any bubbles. The other was using plain water to get the coils to stick together. I was taught that you had to use a thin paste of clay and water known as "slip" to act as a glue for hand built pots. I hope this helps in future projects.

Your supposed to score and slip it

That clay has a wife and children! You can't fire him, he needs this job!

Make the clay and put it in liquid nitrogen, what will happen?

When I as in my ceramics class, my teacher always had us loosely place a plastic bag over our works to either keep them moist and workable for the next day, or to let them dry slowly. If you just leave them out in the open right after working them (probably like what you did), then they dry out and shrink too quickly and that's why they crack. When people say to let ceramics dry slowly, they mean REAL slow, like 2-4 days of slowly letting it dry out.

I wonder if primitive technologys is watching this and is like “lol”

COOL!!-Make a brick wall

you should make a bow and cast some metal arrowheads! :)

Build a remote-controlled clay squishing device, put it in a vacuum chamber with a lump of clay, then squish the clay while under vacuum.

You didn’t slip and score

You da Man Nate! Love the positive attitude! Keep up the good work!

Nate, you're doing a great job. you're pleasant and easy to listen to, and your enthusiasm is evident. I would like to see more of Grant again, maybe more vids with the two of you together.

The Kings of Random another awesome video idea would be if you made a clay turn table for making pottery!!!

I'm so glad you know clay terms

Can you fire clay with the Solar Scorcher?

Could you "wedge" clay in the vacuum tub?

Can you make paper from a tree?

ohhh please do more ceramics! I would love to see if you could build a real in ground kiln in the backyard! also i would love to see more "survival prepper" type videos!

Make a brick wall

Do it again please

Loving the regular uploads, Nat is doing an excellent job too!

I am actually in the middle of experimenting with clay. I was surprised to see this at the same time!

Clay: “First you throw me on the table, then you fire me... 😢😢😢 WHY??? What have a done???”

I made a play button with my clay.

Cool pots!

Thanks me and my little sister are learning to make and use clay in school and that will help a whole lot

Ha nice idea

Can you make a silicone mold for the link sword from a previous video and cast some polyeurethane swords as gifts or maybe cast chocolate into it

hey Kings random I think you should revisit this this project with a homemade clay wheel to throw the clay I feel like you'll have better results.

I'm a ceramicist, and the trick to keeping your clay from cracking is holding it a 200° F for two hours before increasing the temperature. This removes all ambient water. After that, increasing temperature by 300°F per hour is what I do.

If you put food coloring in water and then put it in the distiller you used in a previous video and would the food coloring evaporate with it and land in the top or would it stay behind

Another awesome video, thanks. You should try using your foundry from earlier videos for firing clay of modifying it. It would be cool if you could build a low cost kiln...

I'm in intro to 3D art and I saw this and started watching it as I was working with clay

Make a dry ice bomb (this time with water inside) and put it in a fire and see if it extinguishes!!

You forgot to score the clay before stacking it on itself, That’s probably why they cracked.

Dang ... You made a bowl ... Will wonders never cease ...

Can you use the solar scorcher on clay to see if it will turn to pottery?

Love from India ❤🍻

What happens if we boil gallium.

I absolutely love this guy

That BBQ is 🔥!

wedge the clay... more like beat up

You should try to melt down plastic and cast it into a mold

Thanks for the nice information.. I also want to know, whether you have glazed your bowls before heating? And second, can we heat our pots on gas also... Like putting in a slightly big aluminium rice type container on slow heat..?

I feel like I’m in my ceramics class again just by watching this video

I want to see a portable power bank or power station that you could use as a backup battery at home for when the power is out or if you want portable power. station.

Next Make a pottery wheel!!!!!!!!!!!!!♥♥♥♥ and then the whole set will be completed !!!! XD

People have been firing clay for thousands of years. Technique is the key.

Clay is just amazing

More clay videoes

I miss the deadly electronics projects :(

Living in a place that is pretty much always summer is probably great for doing experiments

Well done a beautiful work 👍, and the most beautiful addition of translation,

Collab with Primitive Technology?

Jingle bells jingle bells jingle all the way oh whats fun to ride a horse completely made of clay

THAT WAS LIT!!!!!!!🔥🔥🔥🔥🔥🔥

I just watched that old Clay video yesterday and asked if you could make and fire casting molds! Lol

What happened to the main guy?

MAKE A CLAY PAN 😀✌

Did that with bunnies i cast in a gipsen mold that i made of a plastic Easter decoration. The pouring-clay i made with powdered clay, dehydrated soda, sodium nitrate and water. The additives will make the clay liquid by breaking up the hydrostatic bonds between the slates of the clay. I poured the clay in the mold and waited for a layer of clay to settle against the wall. then i poured out the rest of the clay. After some drying, i pulled the cast from the mold and let it dry. Then i removed the pouring seems with a knife and some sanding paper. At the next family barbecue, i put my casts in the remaining coals and put some new on top. I raised the temperature to an orangy color with a billow and let them sit until the fire had gone out the next morning. When i pulled them out, some were only just fired, some were so hard they rang like a bell. Did you know that the first ceramics where probably clay beads that had fallen into the fire?

Cant wait for the casting

put the clay in a vaccum chamber before toasting it! Edit : I said toasting but i wanted to Say burning it

When will we see Grants *Big Project?*

Love you're vids

The duke of random has arrived and is here to stay

You should make your own pottery glaze and use it with your DIY clay!

I love your vids

How would the homemade charcoal do in this? Was there a ratio of how much wood charcoal to use for how much of the charcoal here?

Hey I know you like the food and all, but Clay, YOU'RE FIRED MUWAHAHAHAHHAHA!!! So basically, yes, you can fire Clay in a BBQ.

This idea was lit 🔥

Hello sir U are awsome.also the video that u made. U are great. Can u make security system that keep anyoone from room. Or can u make any shocking pen or like that for fun.

King of random you should see what will happen if you put clay in the vacuum chamber? And you guys are cool.

You can add paper pulp (cellulose fiber) or cotton fiber into your clay in a 1:4 or 1:5 ratio, well mixed into a slurry, to add strength and prevent shrinkage and cracking in the drying phase. Also I'm honestly not certain your pots were actually fired. To fire clay they should get red hot past quartz inversion into vitrification and stay there for a few hours, and then cool down very slowly. The goal is to form strong crystalline structures from the heat. Most BBQs only go up to a few hundred degrees in temperature, which only really removes humidity and burns off impurities. Before firing if you tap your fingernail on a dry pot it sounds like wood, but after firing it should sound like porcelain or glass. The way they broke apart proves they didn't get to vitrification...

Where in the world has the king of random been?!

Can the Solar scorcher fire clay???

I have clay class in my high school and i love that class its fun

Gotta love doing pottery. Also, don't underestimate the power of clay slip.
